# Safe Vaping Explained! Ohm’s Law Assures Vape Safety

Is vaping safe? The question has been garnering headlines since the first modern e-cigarette was introduced during the mid-2000s. Although nothing is completely safe and everything comes with some risks, vaping is much safer than traditional cigarettes. It is found to be around 95% less harmful than tobacco cigarettes.

Safety in vaping depends on the device’s usage. If an e-cigarette is used keeping instructions in mind, then it is a reliable and enjoyable device. On the other side, unnecessary experiments with it lead to unwanted circumstances, even when you have purchased the device from the best vape shop in the UK.

A major factor that contributes to the vape safety is a battery. It is important to understand its good points and limitations.

What Is Battery Safety?

A battery is an important and the most crucial part of an e-cigarette. It has the ability to enhance or ruin your vaping experience. To make your device perform well, you need to make sure that its coil builds are doing well with respect to the battery. To calculate the vape safety and safe sub-ohm vaping, there are various types of Ohm’s Law calculators.

Some vape users ignore the importance of Ohm’s Law for vape safety. It is because they think calculating Ohm’s Law for safe vaping is a daunting task, like solving a mathematical equation. But in reality, there’s no magical formula about the law. It’s an effective calculator to understand the relationship between voltage, current, and resistance.

Understanding The Vape Triangle: Voltage, Current, And Resistance

Voltage (V), current (I), and resistance (R) are the main elements of a vape circuit. Here, ‘V’ is the voltage of device’s battery, ‘I’ is the current produced by the coil, and R is the resistance of the coil. The triangle is a link between the three elements and it can be explained through a simple formula:

V/ I*R

To understand the formula, you need to calculate current, resistance and power.

How can you calculate current (I)?

There is a simple formula to determine the current (I). You can derive it from the triangle. All you need to do is simple mathematics. The formula is:

I= V/R

To understand it in the detail, let’s take an example from the real world. Assume that you have a mod with power 4.2V and coil capacity of 0.5 ohm. Now, use the available values to calculate the current.

I= 4.2/0.5

I= 8.4 Amp

Similarly, you can calculate the current with any value of voltage.

How can you calculate resistance (R)?

Like calculating the current, you can use Ohm’s Law to calculate the resistance. The formula for calculation is:

R= V/I

If you have a device with a battery of 10 amp and a maximum voltage of 4.2V, then the safe lower limit will be 0.47 ohm (put the available values in the formula).

How to calculate voltage (V)?

Similarly, you can get the voltage of your device if you have values of current (I) and resistance (R). The formula to calculate it is:

V= I*R

How to calculate wattage (P)?

One of the most useful formulae for safe vaping is wattage (P), also called power. It can be calculated if know the value of voltage and current. The formula to calculate wattage is:

P= V*I

Why Do The Formulae Important?

When it is about the vape safety, calculating I, R, and P is important. It helps you determine the current your device’s coils are producing and the wattage. Ohm’s Law helps in understanding that when we increase resistance (R), current (I) and wattage (P) drop. On the other side, the decreased resistance results in the increased power and current.
